Summary

Cat Shield is a popular option if aesthetics of your undercarriage is important to you; however, Cat Shields are highly specialized to select vehicles with factory defaults, have limited vehicle model coverage, and don't support heavy duty trucks/diesel engines.

CatClamp is more flexible and fits more vehicles, offers more value at the highest level of protection, provides comprehensive DIY installation instructions, and is backed by up to a lifetime money back warranty.

About CatStrap

CatStrap is a steel reinforced strip that runs along the length of the exhaust system. It's secured by four clamps—two at each end of the converter and two at each strap end—and then steel zip ties in between. It is offered bundled with its CatEye electronic alarm system for added protection.

Summary

The CatStrap is generally easy to install, but can be problematic on bendy exhaust systems and requires additional purchase of correct-size exhaust clamps. Reviewers online have noted that visually, the CatStrap may not appear as robust as alternatives, and for that reason many opt to bundle their purchase with the CatEye alarm system. When combined with the recommended CatEye add on, CatStrap is more expensive than equivalent CatClamp kits.

CatClamp offers excellent value at a comparable price given it's highly robust deterrence that is both physical and visual. CatClamp's easy to install, flexible design fits a wide variety of exhaust system configurations - in particular heavy duty, commercial and diesel vehicles. And in terms of theft protection, no competitor yet matches CatClamp's industry leading lifetime limited money back warranty*.
